Abstract
The utility model relates to a high and low temperature chamber for an indicator calibrating installation, which comprises a high and low temperature chamber temperature-control door and a window arranged on the high and low temperature chamber temperature-control door, wherein the window is formed by adopting hollow quartz glass and filling inert gases in a hollow interlayer and attaching an electric heating wire ensuring that the surface of the glass does form dews during the low-temperature test. A macromolecule insulation material is filled around the hollow quartz glass. The utility model ensures that the high and low temperature chamber does not form dews during the low temperature test, has the advantages of good insulation property of the chamber door and accurate, stable and practical calibration of an indicator, and is convenient for operation.
Description
Technical field
The petroleum industry that relates to the utility model detects and uses indicator.Particularly relate to a kind of indicator calibrating installation high-low temperature chamber.
Background technology
The indicator that is used for oil field downhole oil pumping function test is under the simulation oil pump actual working environment temperature conditions, carries out the test of all temps environment, and the accuracy of the data that indicator detects wants regular high-low temperature chamber at the indicator calibrating installation to experimentize.The high-low temperature chamber form of indicator is when doing low temperature test at present, and the glass surface dewfall of its form makes troubles for the interior instrument work of inspection box, and the heat-insulating property of chamber door is also poor in addition.
The utility model content
The technical problems to be solved in the utility model, provide a kind of when low temperature test not dewfall and high insulating effect of form, easy to operate, good stability, the indicator calibrating installation high-low temperature chamber that practicality is good.
The technical scheme that adopts:
A kind of indicator calibrating installation high-low temperature chamber comprises high-low temperature chamber temperature control door and the form that is located on the high-low temperature chamber temperature control door.Described form adopt the hollow quartz glass and in hollow sandwich the filling inert gas, attach when guaranteeing low temperature test glass surface not the electrical heating wire of dewfall constitute.
Above-mentioned form can adopt the multilayer quartz glass to be combined into the hollow quartz glass, vacuumizes the filling inert gas, attaches electrical heating wire and constitute in each interlayer of glass.
Filled high polymer insulation material around the above-mentioned hollow quartz glass.
The utility model has guaranteed that high-low temperature chamber can dewfall when doing low temperature test, and the chamber door good heat insulating is easy to operate, the indicator calibrating accurately, stable, practical.
